TEETERING ROUNDABOUT.

Application mea Februar-y 24, 1922.

T0 all whom t may concer-n.'

Be it known that If, HAROLD C. Ronrrrxn, a citizen of the United States,and a resi dent of Indianapolis, county of Marion, and VState ofIndiana, have invented a certain new and useful Teetering Roundabout;and I do hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,in which like numerals refer to like parts.

This invention relates to an amusement device, and particularly to astructure capable of use as a merry-go-round and teeter. A The chiefobject of the invention is to provide means which will permit asupporting plank to be used as a merry-go-round, or as a teeter whendesired.

One feature of the invention consists in the means for revolving theteeter board by the persons thereon.

Anotheil feature of the invention consists inthe provision of meanswhereby the board is provided with a hand rest and a foot rest.

Another feature of the invention consists in the particular mountingconstruction.

The full nature of th-e invention will be understood. from theaccompanying drawings and the following description and claims.

In the drawings Fig. 1 is a topplan view of the invention.. Fig. 2 is aside elevational view of the same, the dotted lines indicating two otherpositions of. the mechanism when used as a teetering device. Fig. 3 isan enlarged sideelevational viewfof the mounting for the teeter board,parts being broken away to show other parts in section. Fig. 4 is a viewtaken at right angles to Fig. 3, and of the same parts.

In the drawings 10 indicates a teeter board suitably cut away at 11adjacent each end 12. Each ofthe ends 12 provides the usual seat for thechild or person. The board is also longitudinallv slotted adjacent eac-hend, as at 13 for a purpose hereinafter to be'described. The cut awayportion 11 is provided so that the limbs may straddle said board andextend downwardly to engage a depending U-shaped strap 14 which providesa foot rest. The U-shaped strap 14 also carries a transverse shaft orpivot 15, and associated with said shaft are the angularly positionedbraces 16. Pivotally supported upon each of the shafts 15 is a SerialNo. 538,858.

pair of levers 17 which extend upwardly and angularly through the slot13. and said levers are secured together at their upper ends by suitablemeans, such as the handle 18 having the gripping portions 19. The levers17 adjacent the handle portion 1R carry a pin 20, and associated withsaid pin isa connecting rod or cable 21.

Extending through the teeter board 10 is a spindle or pivot 22 which-terminates in an eccentric or crank arm 23' which carries suitablecollars 24. The collars 24 are connected to the other ends of thecablesor connecting rods 21. It is to be understood that the spindle 22is stationary, and the kcrank 23 is rigidly secured thereto inanysuitable manner, as by a pin. It will be readily aps parent thatalternate pulling upon each of;

the 'handle constructions will cause the board to revolve about thepivot 22, thereby` providing a merry-go-round construction whichrequires no assistance from persons standing nearby, or the operation ofsaid merrygo-round bythe persons upon the board engaging the ground withtheir feet.

Suitably secured to the central portion of ther boardv 10 by the boltymeans 25 andV the nut means 26 isa pairof similar pivoty formingYbrackets 27 providing theppivot 28. v'Said brackets vare spacedV apart,as shown clearly in Fig. 4, andare adapted to pivotally support,` bymeans ofl thev pivotv bolts 29, a yoke` construction having the pivotalportion 30 and the depending arms 31. Each of the arms terminates in asocket 32 and the plank 10 carries upon its under side a supportingbracket 33. connecting the bracket 33 with the socket 32 of the arm 31is a tie rod 34, and said tie rod may be detachably associated with saidmembers by having its ends bent anguu larly, as at 35 and 36, and saidends may be apertured for the reception of a retaining member or key,such as the cotter pin 37. From the foregoing it will be readily apparent that when the tie rods are associated with the plank and yoke,said teeter board is incapable of movement about the pivot 28, the axisof which coincides with the bolts 29. When thus secured againstteetering movement, the handles 18 may be alternately actuated to rotatethe board, as a merry-go-round. When it is desired to utilize the boardas a teetering construction, the tie rods 34 are disconnected fromeither the brackets 33 or the sockets 32, or from yDetachably both, andpermitted to hang suspended from the other ii' not entirely detached.Vhen thus released, the board l is adapted to pivot upon the aXis 28hereinbe'tore de scribed, so that the board may operate as a teeteringdevice.

The post or standard for supporting the board and all of the structureis hereinv iilustrated as a tubular member 37 having a threaded end 38adapted to receive a bear ing cap 39. The bearing cap is axiallyapertured, as at LlO, and is transversely apertured, as at 4l. Thetubular member 37 is transversely apertured at 4t2, and said transverseapertures al and l2 are adapted 'to register to receive a set screw 43,which set screw extends inwardly into the tubular member and is adaptedto engage in a socket 44 in the spindle 22 which entends through thecentral or axial opening a() in the cap 39. The yoke is provided with acentral openingl 45 which is adapted to receive said spindle 22, andsaid opening 45 is enlarged at lr6 to receive a ball race 47 forrecucing the `friction between the yoke and cap when used as amerrygoround lt is to be understood, of course, that the pla k l0 isprovided With a longitudinal and centrally positioned aperture i8 topermit ot teetering movement, since the spindle 22 remains stationary insaid movement.

lNhile the invention has been described in great detail in the foregoingspecifications, tlie same is to be considered as illustrative ratherthan restrictive in character, and the many modifications which vvillreadily suggest themselves to those skilled in the art to which thisinvention applies are all considered to be lWithin the purview of thisinvention, reference being had to the appended claims.

The invention claimed is:

l. A teetering roundabout comprising a board having a slot intermediateits ends, a stationary pivot extending through said slot for rotatablysupporting the board, a

second pivot for teeteringly supporting said board upon an axis at rightangles to said first pivot and rotatably supported by said first pivot,and a reversible board rotating construction associated with thestationary pivot, including a pair of handles each pivotally supportednear each end of the board, and an eccentric connected to both handlesand to the stationary pivot.

A teetering roundabout including a board, a centrally apertured yoke, astationary support extending through the yoke aperture and rotatablysupporting said yoke, a teetering support for the board on said yoke,and eccentric means associated with the projecting end of the supportJfor rotating the board.

3. A teetering roundabout including a board, a centrally aprrtured yoke,a stationary support extending through the yoke aperture and rotatablysupporting said yoke, a teetering support for the board on said yoke,eccentric means associated with the projecting end of the support forrotating the board, and a ball race construction interposed between saidstationary support and said yoke.

i. A teetering roundabout board mounting, including a rotatable yoke, anupright support rotatably supporting said yoke, a pivot on said yokeparallel to the board, and means connecting said yoke to the board toprevent tilting movement thereof.

5. A teetering roundabout board mount ing, includin@r a yoke providingone pivot for the teetering board and parallel thereto, an uprightsupport rotatably supporting said yoke, depending arms straddling saidupright and secured to said yoke, and means connecting the ends of thearms with the board for preventing teetering movement thereor" upon thefirst mentioned pivot.

In Witness whereof, I have hereunto atlised my signature.

HAROLD C. ROEMPKE.
